Ndeupi musiyano uripo pakati peHPMC E neK?

HPMC (Hydroxypropyl Methylcellulose) imhando ye cellulose ether inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira mishonga, chikafu, zvizorwa, uye kuvaka.HPMC isiri-ionic, mvura-inonyungudika polima yakabva muselulosi, uye inowanikwa mumhando mbiri: HPMC E uye HPMC K.

HPMC E igiredhi yakaderera-viscosity yeHPMC, uye inoshandiswa zvakanyanya mumishonga yemishonga.Inoshandiswa sebhainda, disintegrant, uye kumisa mumiriri mumapiritsi, capsules, uye granules.Iyo inoshandiswa zvakare seyakakora mumiriri mumasyrups, makirimu, uye ekuzora.HPMC E igiredhi yakaderera-viscosity, zvichireva kuti ine yakaderera viscosity kana yakanyungudika mumvura.Izvi zvinoita kuti zvive zvakanaka kushandiswa mumishonga yemishonga, sezvo zviri nyore kusanganisa uye kuparadzira mumvura.

HPMC K igiredhi repamusoro-viscosity reHPMC, uye rinoshandiswa zvakanyanya mukuvaka uye kugadzira chikafu.Inoshandiswa sechibhainda, chikobvu, uye chinomisikidza muzvinhu zvekuvakisa, sematairi anonamira, magiroti, uye plasters.Inoshandiswawo seyakakora muzvigadzirwa zvekudya, senge jamu, jellies, uye sosi.HPMC K igiredhi repamusoro-viscosity, zvichireva kuti ine viscosity yakakwirira kana yakanyungudika mumvura.Izvi zvinoita kuti ive yakakodzera kushandiswa mukuvaka uye chikafu chekudya, sezvo ichikwanisa kupa gobvu, viscous kuenderana.

Musiyano mukuru pakati peHPMC E uye HPMC K ndiyo viscosity.HPMC E igiredhi yakaderera-viscosity, zvichireva kuti ine yakaderera viscosity kana yakanyungudika mumvura.Izvi zvinoita kuti zvive zvakanaka kushandiswa mumishonga yemishonga, sezvo zviri nyore kusanganisa uye kuparadzira mumvura.HPMC K igiredhi repamusoro-viscosity, zvichireva kuti ine viscosity yakakwirira kana yakanyungudika mumvura.Izvi zvinoita kuti ive yakakodzera kushandiswa mukuvaka uye chikafu chekudya, sezvo ichikwanisa kupa gobvu, viscous kuenderana.

Kuwedzera kune viscosity, HPMC E uye HPMC K inosiyanawo maererano nechimiro chavo chemakemikari.HPMC E ine yakaderera molecular uremu pane HPMC K, izvo zvinopa yakaderera viscosity.HPMC K ine huremu hwemamorekuru hwepamusoro, hunoipa huremu hwepamusoro.

Chekupedzisira, HPMC E uye HPMC K zvakare akasiyana maererano nekunyungudika kwavo.HPMC E inonyungudika mumvura inotonhora, ukuwo HPMC K inonyungudika mumvura inopisa.Izvi zvinoita kuti HPMC E ive yakakodzera kushandiswa mumishonga yemishonga, sezvo inogona kusanganiswa nyore nyore uye yakaparadzirwa mumvura inotonhora.HPMC K yakanakira kushandiswa mukuvaka uye kudya kwekudya, sezvo inogona kusanganiswa nyore nyore uye yakaparadzirwa mumvura inopisa.

Mukupedzisa, musiyano mukuru pakati peHPMC E uye HPMC K ndiyo viscosity.HPMC E igiredhi yakaderera-viscosity, nepo HPMC K iri giredhi repamusoro-viscosity.Mukuwedzera, HPMC E ine yakaderera molecular uremu pane HPMC K, uye inonyungudika mumvura inotonhora, nepo HPMC K inonyungudika mumvura inopisa.Misiyano iyi inoita kuti HPMC E uye HPMC K zvive zvakanaka kuti zvishandiswe mumashandisirwo akasiyana.
